‘Cohort II’ was a major six-year study, funded by the Department for Transport, providing an up-to-date picture of how ‘cohorts’ of learner drivers in Great Britain undertake driver training and testing, and of their subsequent experiences as new drivers.


Questionnaire results from a random sample of 8000 practical test candidates on learning to drive and experiences of newly qualified drivers.

Key Findings:

  • As drivers become more experienced, the proportion of RTIs in towns or on city roads decreases, and the proportion of RTIs on fast dual-carriageways and on motorways increases correspondingly.


New Drivers


Minimal content on motorways for new drivers.
